The invention discloses a double-drum winching machine. The double-drum winching machine comprises a base. An engine, a speed changing device, an external urgent braking device and a transmission system are arranged on the base, wherein the engine, the speed changing device, the external urgent braking device and the transmission system are sequentially connected in a transmission mode; a forward and backward gear mechanism is arranged at the portion, between the engine and the speed changing device, of the base; a torque limiter is arranged at the portion, between the speed changing device and the external urgent braking device, of the base; a first drum and a second drum are respectively connected to the power output end of the transmission system in a transmission mode. The double-drum winching machine is reliable in work, easy and convenient to operate, high in safety, good in braking performance and wide in application range; as the forward and backward gear mechanism is arranged, reversing is convenient, and it is guaranteed that forward traction and backward traction are same; when reversing is carried out, the forward state, the idling state and the backward state can be achieved only by operating a reversing rod, and operation is quite easy; as the torque limiter is arranged, overload operation can be effectively controlled, and overload accidents can be avoided.
